' My invention relates toan improvement 1n door operating devices andmore particularly to the type of operating devlcesemthe same time veryeflicient and a device ployed in connection with stove oven doors ont-heordinary type of range's.

An object of my invention is to provide rected to a means for preventingthe door from accidentallydropping open and a still further object isthe rov ision of a means for checking the, opening movement of the doorbeyon a predetermined point.

A still further objectof my invention is to provide a door operatingdevice which will be neat, small and inexpensive but at which will be solocated that the interior 'erly positioned;

oven space willnot be reduced.

As a further object of the device there is provided means forautomatically closing the oven door and for maintaining it in its closedposition until manually opened.

With the objects above indicated and other objects hereinafter ex lainedinview my 1nven t1on consists int e construction and combmationofelements hereinafter described and claimed.

Referring to the drawings: a

. Fig. 1 shows a 'pers' active view of aportion of the frame of t estove and the oven door attached thereto with my hinge'prop- Fi 2 is arear view of the same showing t e manner in which the hinges are securedto the supporting frame; f

Fig. 3 is a top plan view with the ovendoorshown in. open position andhaving the hinge portion in section; and

Fig. 4 is. a segmentary sectional view through the hinge member showingthey atrangement of the spring and the endof the pivoted arm.

' In h drawings, 10 indicates the frame around the door opening of thelower door of a-stove, not shown. This frame is gro an age a ortion ofthe door to thereby v1 e a tig t joint and thus prevent the fromescaping from within the oven.

vided with an upper and lower flange 11 and side flanges 12 which extendinto the door opening and are of sufiicient width to 10 and At the lowerportion of theiframe 'uplon the'inner surface arecess 13 is provided wieh serves as a portion of a bearing adapted to receive theextension 14formed upon the sides and at the lower ends of the door-15.

The door 15 is provided with flanges 15 and 15! which engage with theflanges 11 and 12 of the frame 10 when the=door15 is in closed position..An ofljset' 16 is formed in the lower portion of the lflanges 15 andthis offset extends inwardly. The .upperi surface .ofthe oflset 16 isprovided with a semi-circular portion 16 and through this portionextends an openin 17.

A block or casting 20 is located within the slot 15 of the door 15 andis secured thereto by means of bolt 21. This block or casting 20 isprovide with a recess 20 which registers with he recess 13 in the frame10 and they both thereby form a bear-n ingfor the extension 14ion thedoor 15.

he block or casting 20 is further provided with a portion 20. which fitswithin a recess 19 formed in the flanges '12. In

fact the entire lower portion of the flange 12 is cut away toaccommodate this block or casting 20. ,The portion 20 of the casting 20is cut off at right angles to the vertical portions to form a flatsurface 23 which acts as an abutment for the door 15' when in openposition as indicated at .36. A recessed portion 20- is provided in faceof-the block or castin 20; and is located so as to register with 't eortion 16'v on the door 15. Adjacent to t is recessed portion 20' isa'slot 20 which extends entirely through 1 the block 20 the purposefor'which will hereinafter explalne A housin castin 20 y meansof'bolts26 which extend t rough openin provided in the .mtegral flanges25. T e opening27 extends 24 is secured the block or I I entirely throuh the housing 24 and aslot 4 28 is provid which extends throughout -theentire lengththereof and commumcates 'with the opening 27. A rod 32 isscrewthreaded into the casting 20 and extends centrally through theopening 27 on the i housing 24.

, An arm 29 has formed at one end a rounded head portion 29* which has acentral opening 29* and a pin 30 extends through this opening 29 and theopening 17 in the offset portion 16. The head portion 29 is adapted tofit within the recess 16 so that the outer surface thereof is inthe"same plane as the outer surface of the flange The arm 29 is bentinwardly at right angles as indicated at 29 and is provided with acircular member 31.

The portion 29 is adapted to slide within the slot 28 and the circularmember 31 is adapted -to slide within the opening 27 of the housing 24.The arm 29 also extends through the slot This circular member 31 has acentral opening 34 which receives the rod 32 and permits the same toslide therein.

A spring 35 is interposed between the circular member 31 and the casting20 and is caused to contract when the door is opened.

The oven walls which are not shown are adapted to be applied in theusual manner and when soapplied completely cover up the device andprevent the heat from coming in contact with it. This is due to the factthat the device is always within an air pocket between the walls of thestove and' the walls of the oven.

In operating the device as the door 15 is opened the arm 29 beingattached thereto and having the circular portion 31 formed thereon iscaused to engage the spring 35 thereby contracting the same. This springprevents the door 15 from hanging open or accidentally flying open andas the door reaches its substantially horizontal position the bottomcorner of the door 15 engages or abuts the surface 23 formed on themember 20 as indicated at 36 and prevents further open movement thereof.

"When it is desired to close the door it is raised slightly from thehorizontal and the springs 35 are of suflicient tension to draw the doorinto closed osition.
